Special Issue Information
Dear Colleagues,
Fifty years ago, Russell A. Hulse and Joseph H. Taylor discovered the first binary pulsar, PSR B1913+16, which enabled precision tests of gravity in strong-field regimes and provided the first evidence of gravitational waves. This groundbreaking discovery also enhanced our knowledge of possible evolution scenarios of binary systems, and initiated precise mass measurement of neutron stars, shedding light on the behaviour of matter under extreme conditions. Since then, pulsars and other compact stars have become essential tools for exploring fundamental physics that would otherwise remain inaccessible. As a cornerstone of modern physics, the concept of symmetry plays a pivotal role in understanding fundamental interactions. Compact stars, such as neutron stars and black holes, serve as ideal laboratories for studying the symmetries of gravitation and particle physics due to their extreme physical conditions.
Nowadays, gravitational wave astronomy has become one of the most active research fields, involving detectors ranging from terrestrial (LIGO, Virgo, KAGRA, ET, CE, etc.) to space (LISA, Taiji, Tianqin, DECIGO, etc.), and even galactic-scale Pulsar Timing Arrays. These studies offer invaluable insights into gravity, the properties of compact stars, stellar and galaxy evolution, as well as cosmology, dark matter and the early universe.
On the occasion of 50 years of the Hulse–Taylor pulsar, this Special Issue aims to gather contributions exploring symmetries in compact stars and recent advances in gravitational wave astronomy. We wish to invite both original and review papers along these lines for this Special Issue.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Symmetry is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
